Signing digital documents is very simple through applications that facilitate this action.

Adobe Acrobat Reader

Adobe Acrobat Reader is an application that has the Portuguese language in the settings, and allows access after the user logs in with their Gmail, Facebook or Apple account, which is linked with an Adobe ID.
